Metal selection for wire array metamaterials for infrared frequencies.

Optics express

Hayashi JG, Fleming S, Kuhlmey BT, Argyros A.
PMID: 26698470
Opt Express. 2015 Nov 16;23(23):29867-81. doi: 10.1364/OE.23.029867.

We analyze the dependence of the electromagnetic properties of wire array metamaterial media on the choice of metal, and identify promising material combinations for use in the near and mid infrared. We propose a figure of merit for the...

Refractive index sensor based on a polymer fiber directional coupler for low index sensing.

Optics express

Lee KJ, Liu X, Vuillemin N, Lwin R, Leon-Saval SG, Argyros A, Kuhlmey BT.
PMID: 25090565
Opt Express. 2014 Jul 14;22(14):17497-507. doi: 10.1364/OE.22.017497.

We propose, numerically analyze and experimentally demonstrate a novel refractive index sensor specialized for low index sensing. The device is based on a directional coupler architecture implemented in a single microstructured polymer optical fiber incorporating two waveguides within it:...

CSF neurofilament light chain reflects corticospinal tract degeneration in ALS.

Annals of clinical and translational neurology

Menke RA, Gray E, Lu CH, Kuhle J, Talbot K, Malaspina A, Turner MR.
PMID: 26273687
Ann Clin Transl Neurol. 2015 Jul;2(7):748-55. doi: 10.1002/acn3.212. Epub 2015 May 25.

OBJECTIVE: Diffusion tensor imaging (DTI) is sensitive to white matter tract pathology. A core signature involving the corticospinal tracts (CSTs) has been identified in amyotrophic lateral sclerosis (ALS). Raised neurofilament light chain protein (NfL) in cerebrospinal fluid (CSF) is...

Metamaterial control of stimulated Brillouin scattering.

Optics letters

Smith MJ, Kuhlmey BT, de Sterke CM, Wolff C, Lapine M, Poulton CG.
PMID: 27176997
Opt Lett. 2016 May 15;41(10):2338-41. doi: 10.1364/OL.41.002338.

Using full opto-acoustic numerical simulations, we demonstrate enhancement and suppression of the SBS gain in a metamaterial comprising a subwavelength cubic array of dielectric spheres suspended in a dielectric background material. We develop a general theoretical framework and present...

Multipole analysis of photonic crystal fibers with coated inclusions.

Optics express

Kuhlmey BT, Pathmanandavel K, McPhedran RC.
PMID: 19529498
Opt Express. 2006 Oct 30;14(22):10851-64. doi: 10.1364/oe.14.010851.

Photonic crystal fibers (PCF) containing coated holes have recently been demonstrated experimentally, but haven't been studied theoretically and numerically thus far. We extend the multipole formalism to take into account coated cylinders, and demonstrate its accuracy even with metallic...

Long wavelength behavior of the fundamental mode in microstructured optical fibers.

Optics express

Wilcox S, Botten L, de Sterke C, Kuhlmey B, McPhedran R, Fussell D, Tomljenovic-Hanic S.
PMID: 19495080
Opt Express. 2005 Mar 21;13(6):1978-84. doi: 10.1364/opex.13.001978.

Using a novel computational method, the fundamental mode in index-guided microstructured optical fibers with genuinely infinite cladding is studied. It is shown that this mode has no cut-off, although its area grows rapidly when the wavelength crosses a transition...

Higher order guided mode propagation in solid-core photonic bandgap fibers.

Optics express

Pureur V, Knight JC, Kuhlmey BT.
PMID: 20588735
Opt Express. 2010 Apr 26;18(9):8906-15. doi: 10.1364/OE.18.008906.

We investigate higher order core-modes of solid-core photonic bandgap fibers experimentally and theoretically. We observe that for some wavelengths ranges the second mode is guided while the fundamental mode is not. We interpret this behavior in terms of the...

Long wavelength anti-resonant guidance in high index inclusion microstructured fibers.

Optics express

Steinvurzel P, Kuhlmey B, White T, Steel M, de Sterke C, Eggleton B.
PMID: 19484102
Opt Express. 2004 Nov 01;12(22):5424-33. doi: 10.1364/opex.12.005424.

Microstructured optical fibers consisting of a low refractive index core surrounded by high index inclusions guide by anti-resonant reflection. Previous experiments considered only wavelengths that are short compared to microstructure dimensions. We experimentally investigate a microstructured fiber with high...

What makes a prognostic biomarker in CNS diseases: strategies for targeted biomarker discovery? Part 2: chronic progressive and relapsing disease.

Expert opinion on medical diagnostics

Kuhle J, Petzold A.
PMID: 23484626
Expert Opin Med Diagn. 2011 Sep;5(5):393-410. doi: 10.1517/17530059.2011.592184. Epub 2011 Jun 15.

INTRODUCTION: Compared with acute neurological conditions, biomarker discovery in chronic progressive and relapsing neurodegenerative diseases may be more difficult. First, the degenerative process may be so slow that the biomarker discovered is released only in small quantities making it...
